Anyways, I haven't finished FFXIII-2 yet (I think I'm around halfway done), but i've already come up with 7 cons
I: FFXIII had WAY better music than FFXIII-2 IMO
II: FFXIII looked a bit sharper in the graphics department
III: FFXIII-2's story is more convoluted, and Noel & Serah know too much about time travel and quantum physics and whatnot, especially that smartass Moogle
IV: Only TWO freaking minigames! TWO!
V: Towns aren't really towns. Just a few amount of people with 3-4 sidequests, a few story bits, limited town interactions, and just Chocolina, no other shop
VI: Once you reach a certain level for a role, you stop learning new moves for that role
VII: You know how in past Final Fantasy games, you cared about the main characters? I don't give two sh!t about Serah or Noel. I want to know what happened to Sazh and his son though.
